Application filed July 31,

To cZZ whom it may concern:

Be it known that I, CLARENCE B. Romans, a citizen of the United States, resident of Seattle, county oi King, State of ashington, have invented certain new and useful Improvements in Bunsen rltttachrnents tor Blowpipes, oi which the following is a specification.

The obj ect of my invention is to provide a blow pipe having a head on which the tip may be conveniently mounted, said head being of such construction that it will form a supporting base tor the tip and hold it in an upright position, or may he uses as a means for hanging up the tip when the burner is not in use.

A. further object is to provide a form of ti on which a Bunsen burner may be easily and quickly mounted.

(Ether objects of the invention will appear ii an the tolloiing detailed description.

The invention consists generally in various cons notions and combinations, all as hereinatt described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

. .gure l is a vertial sectional view through a blow pipe tip and burner embodying my invention,

Figure 2 is a sectional view on the line of Figure 1,

Figure 3 is a sectional view on the line 3*?) of Figure 1,

In the drawing, 2 repesonts a suitable tube through which the mixture of gases tor the blow pipe is conducted! 3 is a base having a passage 4t therethrough communicating with the tube 2 and with the passage 5 et a lip 6 that is tapped into the upper end of the base. The base is preferably flat on the bottom and has a flange 7 thereon provided with a hole 8 and with recesses 9 for hanging up the base on a nail or hook or other suitable supporting means. The walls oi lhe base are of suilicient thickness and weight to support the tip in an upright position. This allows the tip to be placed on a table or bench where it will stand upright without any other supporting means Specification of Letters latent.

than the base and allow the convenient use of the crevice for uniting pieces of metal, porcelain or other material.

Ti lie walls of the passage 5 through the tip have annular steps 10 which are inclined to direct the gases inwardly to the center of the passage and insure a complete i ture thereof before reaching the end of the tip. 7

T he tip is tapered, as shown, and I prefer to provide a. Bunsen burner l1 having a tapered socket to receive the tip so that whenever desired it may be mounted on the tip for use in connection with the blow pipe tor various purposes. This burner is provided with the usual sleeve-like upper portion 12 and the series of ports .13 in the walls thereof near the base. The base supporting the tip may, of course, be made in various sizes and shapes, according to the use for which the device is intended, and there may be any suitable amount of metal in the base, suilicient to render the upright tip stable under all conditions.

In some instances it may be desirable to use the tip in a horizontal position and by providing the base as herein shown I am able to suspend the tip in this way and have both hands tree for supporting the metal or other material to be united.

I claim as my invention:

1. A blow pipe tip and a base therefor having means for connection with a gas supply and provided with a surface for SlllTQOl'tlHg the tip iii an upright position, and said base having means for hanging it and the tip on a suitable support said means including o enings formed in the edge of said base upon opposite sides of said tip and a hole in said base intermediate said openings.

2. The combination, with a blow pipe tip, of a base whoreon said tip is mounted, a gas tube connected with said base, and a flange ru liating from said base and having d openings therein upon opposite sidosbt said tip for suspending the base.

In witness whereof, I have hereunto set hand this 19th day of July 1919.
